Hold on thaaaaaaaarrrrrrrrrrr!!!!!! In the first few paragraphs you speak of increasing your mileage. The rest of the post is about making more power. You don't get something for nothing. Laws of physics will confirm this. So which is it? Do you want more power or better mileage?

ahh, I am a firm believer that you can have both. with efficiency comes power

In my case the poor fuel economy is due to the inability to fully tune the carb in its current configuration.

Max power comes with WOT, economy comes with fine tuning of the idle circuit. Having the ability to make more power comes from making the engine more effecient, or breathe easier, which inturn means better fuel economy (providing I keep my foot out of it )
